So basically 2 weeks ago my iPhone 4S began dieng at 3% now it is up to 13% I took a screenshot after i plugged it in so I could turn it on.. Also I only done little texting, facebook and a bit browsing(wifi) and as you see I don't get over 3 hours usage .. It has gone worse the last long period.. Anything I can do to fix it? Also is there an app to check how healthy my battery actually is.. Like seeing its new max charge amount i mAh which obviously should be lower then the 1600 a new has. Just wona know how low.... Hope someone can help^^

When you press the "Restore" button in iTunes, you will have the option to do a backup of your phone before restoring to new condition. Make sure you do the backup, that way, after you have put your phone back to its original out of the box configuration, you still have the option to restore your last backup to the phone and loose nothing.

I assume that you meant that the phone shut itself down when the battery level reached 15%. The phone can't be much more than a year old yet it sounds like the battery might be dying. My wife's iPhone 4 is about two years old and still going strong so I don't know what to suggest other than call Apple if you still are under Apple Care or if not take a ride to the nearest dealer for your wireless carrier and see what help they may offer. Good luck with it and let us know how you make out.
